Definitions
- the invention relates to a bearing point in a vehicle seat, in particular in a motor vehicle seat, with the features of the preamble of claim 1.
- a locking device with a bearing of this type for locking a fitting of a vehicle seat with a freely pivoting backrest which has a spring-loaded tensioning element for tensioning a pawl and a catch element for supporting the pawl in the event of a crash, the tensioning element and that Catch element are formed in one piece or two pieces with a slot-pin guide as a coupling.
- wishes remain unanswered, for example with regard to the precision requirements in manufacturing.
- the invention is based on the object of improving a bearing of the type mentioned. This object is achieved by a bearing with the features of claim 1. Advantageous refinements are the subject of the dependent claims.
- the mounted element can be in at least two contact points Bearing pins rest and thus be positionally stable over a certain angular range against a change in the acting forces.
- the shaped hole and / or the bearing pin can assume almost all shapes between a single corner (which, for example, is circularly curved except for a rounded corner) and a polygon including a star shape, preferably two straight sections being at an angle of 90 ° to one another. It is sufficient if only one of the partners has such a cross-section. The other partner can then have a circular cross-section.
- the bearing point according to the invention is used in particular in a locking device, specifically in at least one locking element and / or a securing element.
- One of the contact points is preferably approximately in the direction of the contact point between the mounted element and a locking element and / or a control element connected to it, from where the greatest forces are introduced in the event of a crash.
- the two securing elements are preferably mounted on a common bearing pin and both have a shaped hole according to the invention.
- the locking device with the bearing point according to the invention can be used for various adjusters, that is to say both for rotary adjusters such as, for example Fittings for vehicle seats with adjustable backrest and / or freely pivoting backrest, as well as for linear adjusters, such as length adjusters or height adjusters in diagonal struts.
- the locking device according to the invention can also be used for a lock for releasably fastening the vehicle seat to the vehicle structure or for locking different positions of a foldable vehicle seat.
- the locking elements to be secured then differ in their construction, while the securing elements basically remain essentially the same.
- FIG. 1B is a partial section corresponding to FIG. 1A through the exemplary embodiment in the event of a crash
- FIG. 2A shows a partial section corresponding to FIG. 1A in the area of the mounting of a known securing element in the normal case
- FIG. 2A shows a partial section corresponding to FIG. 2A through the mounting of the known securing element in the event of a crash
- Fig. 3 is a partially sectioned view of a fitting
- FIG. 4 is a schematic representation of a vehicle seat.
- a fitting 1 designed as a locking fitting for a vehicle seat 3 is provided with a fitting lower part 5 which is fixed to the structure of the seat part and which has two essentially flat, joined-together plates defining a space for the lower part 5 of the fitting, and with a flat upper part 8 of the fitting which is fixed to the backrest structure and which is at least partially within the space of the lower fitting part 5 and is rotatable relative to the lower fitting part 5 about a backrest bolt 10.
- the vehicle seat 3 has two mirror-image detent fittings 1, which support the backrest of the vehicle seat 3 so that it can be tilted and pivoted.
- a gear rim 12 curved around the backrest pin 10 in the area facing away from the backrest and on the bottom part 5 there is provided a pawl 15 pivotally mounted on a pawl bearing pin 13, the pawl 15 being the first Interlocking element and the ring gear 12 cooperate as a second locking element depending on the relative position of the fitting parts 5 and 8 under tooth engagement.
- a securing device 21 for this locking device 11 has, as a first securing element, an essentially flat clamping eccentric 23 which is pivotably mounted on a bearing pin 25 of the lower fitting part 5 on the side of the pawl 15 facing away from the ring gear 12.
- a prestressed coil spring 27 presses the tensioning eccentric 23 against a control cam 29 which is connected to the pawl 15 in a rotationally fixed manner, so that the pawl 15 is pressed with its teeth into the ring gear 12.
- the securing device 21 also has, as a second securing element, an essentially flat catching element 31, which is likewise pivotably mounted on the bearing pin 25.
- the catch element 31 is normally arranged at a small distance from the pawl 15 in relation to the tooth height and is interposed by a prestressed one arranged in a receptacle of the catch element 31 Clamping eccentric 23 and catch element 31 acting, helical closing spring 33 pressed against a stop 35 fixed to the lower part of the fitting.
- a torque acts on the upper fitting part 8, which has an opening effect on the pawl 15 and attempts to push the clamping eccentric 23 back.
- the pawl 15, however, is supported on the catch element 31 after a minimal pivoting movement in such a way that the tooth engagement between the pawl 15 and the ring gear 12 is retained.
- the clamping eccentric 23 and the catching element 31 are coupled to one another via a slot-pin guide, consisting of an unlocking bolt 37 on the catching element 31 and a link 39 curved around the bearing pin 25 and formed in the clamping eccentric 23.
- a slot-pin guide consisting of an unlocking bolt 37 on the catching element 31 and a link 39 curved around the bearing pin 25 and formed in the clamping eccentric 23.
- the clamping eccentric 23 sits on the bearing pin 25 with a shaped hole 43, the shaped hole 43 having a slightly larger cross section than the bearing pin 25 designed with a circular cross section.
- a resulting force F then acts, which is oblique to the connecting line between the contact point K and runs the center of the bearing pin 25 and defines the contact of the clamping eccentric 23 on the bearing pin 25.
- the shaped hole 43 is not formed with a circular cross-section, but is additionally provided with four radius enlargements, which can also be regarded as strongly rounded corners of a square, with no jumps in the slope, so the shaped hole 43 is a smooth edge. has a convex cross-section. Due to the selected shape of the shaped hole 43, the clamping eccentric 23 bears on the bearing pin 25 with two contact points B, whereby “touching” is to be understood as a tangential contact. One of the contact points B lies - as seen from the bearing pin 25 - approximately in the direction of the contact point K. with the control cam 29, thus ultimately the pawl 15.
